Abu Sa‘d says that once I saw Sayyiduna Wathilah in the mosque of Damascus during prayer; he spat to his left under his foot and rubbed it with his foot. When he finished the prayer, I said to him: "You are a companion of the Prophet (peace be upon him), yet you spit in the mosque?" He replied: "I saw the Prophet (peace be upon him) doing the same."
